i This invention-relates to Van ice cutting device and has for its`primary object the provision of an instrument which can be einployed toquickly and accurately cut a block of icey along any desired line.v

Another object of the invention is the provision, ina manner ashereinafter set forth, of a device which, when used upon the usual blockof manufactured ice, can be lemployed to cut .a piece of desiredweight.`

A'still further object of the present invention is to; provide an icercutting device which will perform the `cutting voperation with a minimumof wastage through the formation of chips. Y

The invention will be best understood from i a consideration ofthefollowing detailed de-y scription'taken in connection with the accom-Y panying drawings forming a part of the .present invention, with 'the'understanding, howv ever, that the invention isrnotconfined toy anystrictconformitvwith the showing of the drawings Ybut may be changed orfmodified, so long as such changes or modifications mark no materialdeparture from the salient feav tures of therinvention as expressed inthe appended claim.

brought together in the manner hereinafter described, a section of icewill be removed equivalent to one third tihe entire weight of' theblock, or in other words there will be removed a block of ice weighingfifty pounds. It is of course understood that when the device is iisedfor removing fifty pound pieces of ice from a block which normallyweighs one hundred and fifty pounds the block is laid upon onelongitudinal edge with the gage bar resting upon and extendinglengthwise ofthe op osite or upper loiigituinal edge thus making t e cuttransversely of the block. It

will be obvious that further cuts can be made in a similar manner todivide the piece into twenty-five and twelve and one half poundsections.

From the description of the structure of the present ice cutting deviceit is believed that.

the operation of the saine will be obvious, for, when the jaw arms arearranged upon opposite sides or against opposite faces of an icel blockand the crank members 19 actuated to rotate the pinion gear 18 it willbe readily seen that the bar 5 will be moved longitudinally of theadjacent bar t3 thus brinvinfv the jaw arms 3 and 4 together forcing thespikes 7 into y the adjacent faces of the body of ice.

Thisactioncauses the ice block to split in aV straight transverse linewith a minimum of chipping.
